| == Introduction ==
| |
|
| |
|
| Please write a clear, concise description of your topic here.You will likely reference your introduction from somewhere else. Please use the following syntax at the end of each of your ideas. '''IT IS CRITICAL YOU ATTRIBUTE''' others work. Your introduction should be factual. No more than 3 or 4 sentences, please. Because you are not an expert in your topic, I expect you to triangulate your information. LOTS OF LINK TO OTHER RESOURCES PLEASE! If you do not use a section, please delete it. Your finished page should only have information which explains your topic.
| | Double-spending is a potential flaw in a digital cash scheme in which the same single digital token can be spent more than once. Unlike physical cash, a digital token consists of a digital file that can be duplicated or falsified. <ref>https://en.wikipedia.org/wiki/Double-spending</ref> |

| == How does it work or a deeper look ==
| |
|
| |
| * If you are discussing a THING YOU CAN TOUCH, you must explain how it works, and the parts it is made of. Google around for an "exploded technical diagram" of your thing, [http://cdiok.com/wp-content/uploads/2012/01/MRI-Technology.jpg maybe like this example of an MRI] It is likely you will reference outside links. Please attribute your work.
| |
| * If you are discussing a PROCESS OR ABSTRACT CONCEPT (like [[fuzzy logic]]) you must deeply explain how it works.
| |
|
| |
| == Examples ==
| |
|
| |
| Please include some example of how your concept is actually used. Your example must include WHERE it is used, and WHAT IS BENEFIT of it being used.
| |
|
| |
| == Pictures, diagrams ==
| |
|
| |
| Pictures and diagrams go a LONG way to helping someone understand a topic. Especially if your topic is a little abstract or complex. Using a picture or diagram is a two part process:

|
| |
| == External links ==
| |
|
| |
| * It would be helpful
| |
| * to include many links
| |
| * to other internet resources
| |
| * to help fellow students
| |
| * Please make sure the content is good

Double-spending is a problem in which the same digital currency can be spent more than once. ... It is not ideal for the same digital currency to be spendable more than once, because it can result in a loss of trust in that currency, making it effectively worthless.[2]
Double-spending is a potential flaw in a digital cash scheme in which the same single digital token can be spent more than once. Unlike physical cash, a digital token consists of a digital file that can be duplicated or falsified. [3]
